I have a container A (not at the origin) and, inside this container, an 
object B at a random location. Using trace() I want to determine what is 
the closest distance between B and the boundary of A in the X-Z plane, 
and use the normal of A at that (approximate) location to 
Reorient_Trans() B.

My main problem is shooting rays around from B as I have trouble 
rotating the ray direction vector around the local Y-axis. I experiment 
with vaxis_rotate() but do not get consistent results as it seems that 
the axis (always?) passes through the origin.

How should I write this code?

Thanks!

Thomas
